The end is fixedly connected to the fixing bolt 42, the fixing bolt 42 is rotatably connected to the limiting plate 44, the left side of the limiting plate 44 is fixedly connected to the lever 45, the fixing frame 41 is snapped into the filter plate 5, the sewage discharge structure 6 includes the spiral rod 62, the left end of the water tank 1 is rotatably connected to the spiral rod 62, the diameter of the spiral rod 62 is the same as the diameter of the sedimentation tank 3, the installation structure 4 facilitates the installation and disassembly of the filter plate 5, facilitates the cleaning or replacement of the filter plate 5, the operation is convenient and quick, the sewage discharge structure 6 can clean the impurities in the sedimentation tank 3, the operation is convenient and quick.

[0024] Furthermore, the left side of the water tank 1 is fixedly connected to the inlet pipe 11 and the return pipe 13, the right side of the water tank 1 is fixedly connected to the outlet pipe 12, and the front side of the water tank 1 is fixedly connected to the drain pipe 14. Solenoid valves are installed on the inlet pipe 11, the outlet pipe 12, the return pipe 13 and the drain pipe 14. Water is added to the water tank 1 through the inlet pipe 11. The water flow is first deposited at the left end by the inclined plate 2. The water is filtered by the filter plate 5. The filtered water enters the mold through the outlet pipe 12 and then returns to the water tank 1 through the return pipe 13.

[0025] Furthermore, the fixing bolt 42 is slidably connected to the washer 43, which is located between the limiting plate 44 and the fixing frame 41. The friction between the limiting plate 44, the washer 43, and the fixing bolt 42 provides resistance to the rotation of the limiting plate 44, thereby fixing the angle of the limiting plate 44. The paddle 45 is moved to make the limiting plate 44 rotate.

[0026] Furthermore, the right side of the limiting plate 44 is fixedly connected to the buckle 46, which is made of nylon and has a certain degree of elasticity. The outer wall of the frame of the fixed frame 41 and the filter plate 5 are both provided with slots corresponding to the buckle 46.

Power is supplied to the motor 61 through an external power source, and control signals are sent through the control console to realize the functions of starting, stopping, speed adjustment, and rotation direction of the motor 61.

[0030] Working principle: During use, water is added to the water tank 1 through the inlet pipe 11. The water flow is first deposited on the left end by the inclined plate 2, and then filtered by the filter plate 5. The filtered water enters the mold through the outlet pipe 12, and then returns to the water tank 1 through the return pipe 13. When the filter plate 5 needs to be replaced, the spring latch 410 is opened, so that the spring latch 410 no longer fixes the position of the fixing frame 41. The handle 49 is pulled, so that the handle 49 moves the baffle 47 forward, thereby pulling out the fixing frame 41 by the inclined plate 2. The lever 45 is moved, so that the lever 45 drives the limiting plate 44 to rotate, so that the buckle 46 no longer locks into the frame of the filter plate 5. Once snapped onto the fixed frame 41, the filter plate 5 can be removed for cleaning or replacement. The installation structure 4 facilitates the installation and removal of the filter plate 5, making cleaning and replacement easy. The operation is convenient and quick, and easy to use. When it is necessary to clean the impurities in the sedimentation tank 3, the drain pipe 14 is opened, and the motor 61 is turned on at the same time. The motor 61 drives the screw rod 62 to rotate, which pushes the impurities in the sedimentation tank 3 forward, and pushes the impurities out of the water tank 1, thereby discharging the impurities. The drain structure 6 can clean the impurities in the sedimentation tank 3, making the operation convenient and quick, and easy to use.
